CROSS REFERENCE TO RELATED APPLICATION

This application claims priority to U.S. Provisional Patent Application Ser. No. 61/812,587 which was filed on Apr. 16, 2013, the entirety of which is incorporated by reference herein.

TECHNICAL FIELD

The present disclosure relates to electric motorcycles, and in particular embodiments, electric motorcycles that include crash bars, as well as processes for modifying electric motorcycles to include crash bars. In particular embodiments, the present disclosure provides police motorcycles as well that include crash bars.

BACKGROUND

Recently it has become important to utilize electric vehicles in many forms as transportation under the belief that the use of electric vehicles is an environmentally conscious decision. As part of this wave of electric vehicles, the electric motorcycle has been developed. The electric motorcycle presents unique technical challenges to utilize the electric motorcycle as motorcycles have been utilized in all facets of transportation. As an example, motorcycles in the past have been utilized as police motorcycles, enabling singular officers to manipulate traffic and transport singular officers between points quickly and efficiently. However, electric motorcycles are designed with lighter frames and components, making the use of traditional components on electric motorcycles in some circumstances unfeasible. The present disclosure provides crash bars for these electric motorcycles that have heretofore not been utilized.

SUMMARY OF THE DISCLOSURE

Electric motorcycles having crash bars are provided with the electric motorcycles including an electric motorcycle frame supported by a front wheel and a rear wheel. The frame can further provide support for a seat to support a rider, a front portion of the frame being configured to engage forks that engage the front wheel. The front portion can also extend from a rocker portion of the frame upward to engage the forks. The electric motorcycle with crash bars can include opposing crash bars coupled to the frame of the electric motorcycle, with the crash bars being coupled to opposing portions of the rocker portion of the frame.

Processes for modifying electric motorcycles are also provided, and these processes can include providing crash bars to the electric motorcycles. The processes can include providing an exposed electric motorcycle frame, with the frame being exposed about a rocker portion and the extension between the rocker portion and the forks. The process can go on to provide coupling a support member across the extension between the rocker portion and the forks. The process can also include coupling a lower portion of the crash bars to the rocker portion, and to the support members.

The present crash bar design can prevent frame collapse and/or battery damage during collision and/or bike accidents.

DESCRIPTION

This disclosure is submitted in furtherance of the constitutional purposes of the U.S. Patent Laws “to promote the progress of science and useful arts” (Article 1, Section 8).

Electric motorcycles and processes of modifying electric motorcycles to include crash bars will be described with reference to FIGS. 1-7. Referring first to FIG. 1, a classic electric motorcycle 10 is shown that includes front portion 12. Front portion 12 includes rocker portion 14 extending to couple with forks 16. As can be seen, electric motorcycle 10 can be supported by wheels 18 and provide a seat 20 for a rider above the frame that includes rocker portion 14. Rocker portion 14 can extend via frame portion 22 to couple with forks 16 of motorcycle 10.

Referring next to FIG. 2, a support member 30 is shown that includes an elongate member 32. Elongate member 32 can be a tubular member and as with all components of the crash bar assembly, can be constructed of plain carbon steel, for example. Extending normally from the ends of elongate member 32 can be members 34. Members 34 can be configured as plate members rounded on either edge, and can extend from a substantially larger portion to a smaller portion. At the ends of these smaller portions can extend fit members 36. Fit members 36 can be hollowed members that extend normally from plate members 34 and are configured to engage a portion of crash bars to be coupled therewith. Item 38 can be utilized to brace or couple with portion of the upper frame member 32 of motorcycle 10, for example. The wall thickness of these members can be approximately 2.5 mm and the length of plate member 34 from connection point to connection point can be approximately 43.4 mm. The width of support member 32 can be approximately 218 mm, while the overall width of support member 30 can be 312 mm. The overall length of plate members 34 can be 72 mm as well.

Referring next to FIGS. 3A and 3B, brackets 30A and 30B for attaching the support member 30 to frame 22 of motorcycle 10 are disclosed. Again, these brackets can be constructed of carbon steel and have a thickness of approximately 6 mm. As can be seen, these brackets are mirror images of one another and are to be placed at opposing edges of frame portion 22.

Referring next to FIG. 4, a crash bar 40 is disclosed that includes a tubular member extending from a coupling end 42 to an opposing end 44. Extending between opposing end 44 and end 42 of the tubular member is a straight portion 46. This straight portion 46 can tie end 44 to the tubular portion of crash bar 40. In accordance with example implementations, the member can form a loop that includes curved portion 48 and straight portion 46. At the terminus of straight portion 46, terminus 50 can be configured to couple with slip fit portion 36 of support member 30. Again, this component can be constructed of carbon steel, and may have a wall thickness of 2.5 mm and the plate brackets may have a thickness of approximately 6 mm.

Referring next to FIG. 5, a crash bar 60 is shown to be placed on the left portion of the motorcycle, and can be considered a mirror image of crash bar 40 shown in FIG. 4. As can be seen, the elongate member of the crash bar extends from terminus 62 and loops through curved portion 68 to terminate in end 64. Extending between end 64 and the other portion of the elongate member is straight portion 66. Straight portion 66 can have a terminus 70 which is configured to couple with slip fit portion 36 of support member 30. Terminus 70 can be threaded to receive a bolt or screw. Again, this can be constructed of the same materials as the crash bar of FIG. 4.

A bolt or screw can be extended through planar portion 34, then through the single opening in 30A or B depending on the side being installed, and then into terminus 70, coupling components 30, 30A, and individual crash bars to form an assembly.

Referring next to FIG. 6 a shell crash bar assembly is shown aligning components 40 and 60 about component 30 with component 30 being coupled to frame portion 22. These components can be coupled to one another with fasteners such as screws and/or bolts for example.

Finally, referring to FIG. 7, in a completed form, the crash bars are shown attached to a police motorcycle. In accordance with example implementations, the police motorcycle can include crash bars 40 and 60 coupled to the frame and supported by support member 30. An example of a completed motorcycle is shown in the 2014 Zero DS Police motorcycle brochure filed herewith, the entirety of which is hereby incorporated by reference herein.
